A TOOL FOR ALLOCATING PERIODIC REAL-TIME TASKS TO A SET OF PROCESSORS

We describe the design and implementation of a tool for applying rate- monotonic scheduling (RMS) technology in distributed environments that serve real-time applications. Our tool, DRMS, enables users to define sets of real-time tasks and the processors to which the tasks will be allocated. The tool finds allocations such that real-time constraints of the tasks are guaranteed. Several feasibility tests can be applied by users to evaluate the feasibility of task allocations. Users can v ary the descriptions of tasks and processors so that DRMS is a practic al tool for designers of real-time systems.
